<p>Does perf rlo use a rustc that's compiled with jemalloc or with the system allocator? Aiui not all platforms use jemalloc so depending on the config it be underestimating allocation costs.</p>

<p>Yes, we use a stock x86_64-unknown-linux-gnu compiler built in rust CI, which currently uses jemalloc as far as I know.</p>
